Label the diagram.
$(A)$ This is which part of a dicotyledonous plant?
$(B)$ If we remove part $1$ from the plant,what will happen?

(N/A) The diagram represents the shoot apical meristem of a dicotyledonous plant.
$(b)$ If we remove part $1$ (the shoot apical meristem),the phenomenon of apical dominance is lost. This leads to the inhibition of the apical bud and promotes the growth of axillary buds,causing the plant to become bushier.
Labeling:
$1 \rightarrow$ Shoot apical meristem
$2 \rightarrow$ Leaf primordium
